[PATCH 01/13] builtin-apply.c: refactor small part that matches context

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This moves three "if" conditions out of line from find_offset()
function, which is responsible for finding the matching place in
the preimage to apply the patch.  There is no change in the
logic of the program.
